ANTIERIC'IION FIFTH-WHEEL.

Specification of Letters Patent.

Patented Nov. 22, 1910.

To all whom t may concern:

Be it known that I, SAMUEL C. BAUCUM, a citizen of the United States,residing at McAlester, in the county of Pittsburg and State of Oklahoma,have invented new and useful lmprovements in Antifriction Fifth- Wheels,of which the following is a specification.

This invention relates to new and useful improvements in fifth wheelsfor vehicles or other like conveyances and has for one of its objects toprovide a device of the class inentioned providing for the front axle, acentral ball bearing pivotal seat and a pair of segmental guidingsections which are so constructed and braced as to eliminate practicallyall friction from the same when the said vehicle or conveyance isunevenly weighted.

Another object of this invention is the production of a device for thepurpose disclosed, providing a novelly constructed king bolt, which canbe readily attached to the front axle of a vehicle or the like withoutthe necessity of boring a hole therein for the reception of the samewhich would consequently weaken the said axle.

A further object of this invention is to provide a fifth wheel whichwill be comparatively simple in construction, cheap to manufacture, andwhich will comply with all the necessary requirements of such a device.With these and other objects in view this invention consists in certainnovel formations, combinations and arrangements of parts to behereinafter more fully described, claimed and illustrated in theaccompanying drawing, in which Figure 1 is a top plan view of myimproved fifth wheel. Fig. 2 is a side elevation of the same. Fig. 3 isa rear elevation. Fig. 4 is a vertical longitudinal sectional viewthereof. Fig. 5 is a bottom plan view. Fig. 6 is a detail perspectiveview of the king bolt.

Referring to the drawings by characters of reference the numeral 1designates a fragment of the front springs of a vehicle (not shown)which is retained upon the head-block 2 by means of an overlyingclamping plate 3, the opposite ends of which are provided with laterallyextending apertured offset ends 4.

A pair of diverging sockets 5 for the reception of the reach bars (notshown) extend integrally from a plate 6 secured to i the forward side ofthe head-block 2 by bolts or other fastenings 7 and have formed in-vtegrally upon their under sides the upper segmental section 8 of thefifth wheel. A transverse plate which is an integral part of the plate 6connects the ends of the segmental section 8 and is clamped to the underside of the head-block 2 by U-shaped clips or straps 10, the upperthreaded ends of which pass through the apertured ends 4 of the clampingplate 3 and receive retainlng nuts 11.

The clamping plate 3 is provided with a forwardly extending bifurcatedbracing arm 12 the outer ends of which are secured to the divergingextensions 5. The bolts 7 which secure the plate 6 to the front of thehead block 2 pass through the same and through apertures formed in theopposite ends of a plate 13 and secure the said plate to the rear sideof the head-block.

The lower segmental section 14 of the fifth wheel is adapted to underliethe upper section 8 and is connected at its ends by a transverse plate15 which rests upon the axle bed 17 A recess or seat 18 is formed withinthe upper face of the plate 15 and receives the cross head 19 of aT-shaped king bolt 20 the upper end of which is reduced and threaded asat 21 and adapted to pass through openings 22, 23, 24 and 25 formed inthe plate 9, head block 2, front springs 1 and clamping plate 8respectively and receive upon its threaded end a suitable nut 26.U-shaped straps or clips 27 serve to hold the cross head 19 within thesocket 18 and pass around the plate 15, axle bed 17, front axle 28 andthrough apertured ears 29 formed upon the ends of a bowed plate 30 andprevent any displacement of the several parts from their normalpositions.

A yoke 81 extends downward from the plate 13 and then forwardly as at 32between the plate 80 and front axle 28, terminating in a forked outerend 33, the ends of which are bifurcated as at 34 and secured uponeither side of the lower segmental section 14 by bolts 83 and 36. Thebolts 36 pass through the socketed extensions 5 and reach bars (notshown) while the bolts 35 not only pass through the socketed extensionsand reach bars, but through the outer ends of the bracing arm 1Qsecurely connect them with the said extensions. The

l bowedplate 30 is provided at its intermediate point which liesdirectly under the king 'durableand so constructed as to fulfil all ofthe necessary requirements of a device forthe purposes hereinbeforedisclosed.

Having thus fully described the invention, what I claim as new, is

l. A device for the purposes disclosed comprising a pair of segmentalsections one of which is adapted to overlie the other section, platesconnecting the ends of the seg- Y mental sections, one plate beingsecured to the head block of a wagon, the other being secured to theaxle an axle bed of a wagon, and a yoke one end of which is secured tothe upper segmental section and the other end to the head blockextending under the axle and providing a ball bearing support for thesame.

2. A device for the purposes disclosed comprising a pair of segmentalsections one of which is adapted to overlie the other section,`platesconnecting the ends of the sections, one plate being` secured to thehead block of a wagon, a clamping plate adapted to overlie the headblock and clamp therebetween the spring of the wagon, offsetaperturedears formed upon the ends of the clamping plates, U-shapedbands or clips securing the clamping plate and one connecting plate tothe head block, an L plate extending from one of the connecting plates,socketed extensions projecting from the L plate and forming an integralbrace for one segmental section, an arm extending` from the clampingplate and connected to the socketed extensions to form a brace for thesame, the connecting plate for the other segmental section being securedto the axle and axle bed by means of U bands or clips and a yoke securedto one segmental section and extending under the axle to provide a ballbearing support forl the same.

5. A device for the purposes disclosed comprising'a pair of segmentalsections one of which is adapted to overlie the other section, platesconnecting the ends of the sections one of which is secured to the headblock of a wagon, a clamping plate adapted to overlie the head block andclamp therebetween the front springs of the wagon, apertured ears formedupon the ends of the clamping plate, U-shaped bands'or clips securingthe clamping plate and one of the connecting plates to the head block,an L platel extending from one of the connecting plates verticallyadjacent the side of the head block, socketed extensions projecting fromthe L plate and forming an integral brace for one segmental section, anarm extending from the clamping plate and connecting with the socketedextensions to form a brace for the same, the connecting plate for thelower segmental section adapted to rest upon the axle bed of the wagon,a bowed plate secured to the under side of the axle of the wagon,apertured ears formed upon the ends of the plate, U bands or clipssecuring the connecting plate of the lower segmental section and thebowed plate to the axle and axle bed, a king bolt, the head of which isseated in a recess formed in the lower connecting plate, extendingupward through apertures located in the upper connecting plate, headblock, springs, and clamping plate, a nut upon the end of the king boltto hold the several parts against displacement, and a yoke extendingdownward from a plate connected with the L plate upon the opposite sideof the head block, under the axle and forward to the socketed extensionsand forming a ball bearing rest or support for the axle of the wavon.
